Georgia, US – Kingspan Insulated Panels’ North American business has teamed up with Atlanta-based Belter Tech to prevent PIR production waste going to landfill. Belter manufactures building materials from reclaimed waste products.
First, the insulation waste is granulated, and this is then blended with cement to create a concrete product, Belter Therm. This can be used for floor and wall infill. Using the PIR waste allows the cement content of the material to be reduced.
“Combining our innovative patent pending mix with Kingspan’s PIR waste not only diverts landfill waste but also enhances the performance of concrete,” said Gerry Hughes, Belter Tech founder and CEO. “By optimising air incorporation and improving water hydration, Belter Tech has created a construction solution that reduces stress cracks during curing and eliminates the need for air entrainment for freeze-thaw cycles. This provides increased density and durability which ensures a stronger finished outcome thus improving the anticipated longevity of the build.”
Kingspan sustainability director Brent Trenger added that initiatives like this might also highlight how end-of-life insulation could be used as a raw material for new products in the future, too.
